@donho Do newer versions completely deprecate L_JS all together? In order to make a plugin backwards compatible, would a plugin have to first check the N++ version with NPPM_GETNPPVERSION and if it is less than v6.8.4 use L_JS and if it is v6.8.4 and greater, use L_JAVASCRIPT?

Yes, that’s right. L_JS is used for embeded javascript so only internal use in Notepad++.
